H-Bridge 11 Click

H-Bridge 11 Click is a compact add-on board that allows a voltage to be applied across a load in either direction. This board features the MAX22200, an octal serial-controlled solenoid and motor driver from Analog Devices. The MAX22200 is SPI-configurable and rated for an operating voltage range from 4.5V to 36V. Each channel features a low impedance push-pull output stage with sink-and-source driving capability up to 1A RMS driving current. Its internal half-bridges can be configured as low-side or high-side drivers, supports two control methods (voltage and current drive regulation), and features a full set of protections and diagnostic functions.

• Author : Stefan Filipovic
• Date : Feb 2023.
• Type : SPI type

Software Support

We provide a library for the H-Bridge 11 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for H-Bridge 11 Click driver.

Standard key functions :

• hbridge11_cfg_setup Config Object Initialization function.

  void hbridge11_cfg_setup ( hbridge11_cfg_t *cfg );

• hbridge11_init Initialization function.

  err_t hbridge11_init ( hbridge11_t *ctx, hbridge11_cfg_t *cfg );

• hbridge11_default_cfg Click Default Configuration function.

  err_t hbridge11_default_cfg ( hbridge11_t *ctx );

Example key functions :

• hbridge11_get_fault_pin This function returns the fault pin logic state.

  uint8_t hbridge11_get_fault_pin ( hbridge11_t *ctx );

• hbridge11_read_flags This function reads and clears the fault flags from the status register.

  err_t hbridge11_read_flags ( hbridge11_t *ctx, uint8_t *fault_flags );

• hbridge11_set_motor_state This function sets the operating state for the selected motor from the half-bridge pairs 0-1, 2-3, 4-5, or 6-7.

  err_t hbridge11_set_motor_state ( hbridge11_t *ctx, uint8_t motor, uint8_t state );

Example Description

This example demonstrates the use of the H-Bridge 11 Click board by driving the DC motors connected between OUT0-OUT1 and OUT2-OUT3 in both directions.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    hbridge11_cfg_t hbridge11_cfg;  /**< Click config object. */

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.
    hbridge11_cfg_setup( &hbridge11_cfg );
    HBRIDGE11_MAP_MIKROBUS( hbridge11_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == hbridge11_init( &hbridge11, &hbridge11_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( HBRIDGE11_ERROR == hbridge11_default_cfg ( &hbridge11 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    log_info( &logger, " Application Task " );
}

Application Task

Drives the motors connected between OUT0-OUT1 and OUT2-OUT3 in both directions in the span of 12 seconds, and logs data on the USB UART where you can track the program flow.

void application_task ( void )
{
    hbridge11_set_motor_state ( &hbridge11, HBRIDGE11_MOTOR_SEL_0, HBRIDGE11_MOTOR_STATE_FORWARD );
    hbridge11_set_motor_state ( &hbridge11, HBRIDGE11_MOTOR_SEL_1, HBRIDGE11_MOTOR_STATE_FORWARD );
    log_printf( &logger, "\r\n MOTOR 0: FORWARD\r\n" );
    log_printf( &logger, " MOTOR 1: FORWARD\r\n" );
    hbridge11_check_fault ( );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    hbridge11_set_motor_state ( &hbridge11, HBRIDGE11_MOTOR_SEL_0, HBRIDGE11_MOTOR_STATE_BRAKE );
    hbridge11_set_motor_state ( &hbridge11, HBRIDGE11_MOTOR_SEL_1, HBRIDGE11_MOTOR_STATE_BRAKE );
    log_printf( &logger, "\r\n MOTOR 0: BRAKE\r\n" );
    log_printf( &logger, " MOTOR 1: BRAKE\r\n" );
    hbridge11_check_fault ( );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    hbridge11_set_motor_state ( &hbridge11, HBRIDGE11_MOTOR_SEL_0, HBRIDGE11_MOTOR_STATE_REVERSE );
    hbridge11_set_motor_state ( &hbridge11, HBRIDGE11_MOTOR_SEL_1, HBRIDGE11_MOTOR_STATE_REVERSE );
    log_printf( &logger, "\r\n MOTOR 0: REVERSE\r\n" );
    log_printf( &logger, " MOTOR 1: REVERSE\r\n" );
    hbridge11_check_fault ( );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    hbridge11_set_motor_state ( &hbridge11, HBRIDGE11_MOTOR_SEL_0, HBRIDGE11_MOTOR_STATE_HI_Z );
    hbridge11_set_motor_state ( &hbridge11, HBRIDGE11_MOTOR_SEL_1, HBRIDGE11_MOTOR_STATE_HI_Z );
    log_printf( &logger, "\r\n MOTOR 0: DISCONNECTED\r\n" );
    log_printf( &logger, " MOTOR 1: DISCONNECTED\r\n" );
    hbridge11_check_fault ( );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
